On behalf of Expert Village, my name's Tom Roland and we're at Cottonwood Motor Sports, and I'm here to tell you about doing a service on a Polaris, quad and this is fairly representative of many of them. On the Polaris' when we do a service, we generally take all four wheels off of it and put it up on jacks and stuff so that we can get a good look at everything, makes it a lot easier to see what we're doing. Take the tire off, and the wheel, and behind there you have a front brake, a disc brake, and with your disc brakes you want to make sure that the discs aren't scored or bent or damaged very much well at all, and you also want to make sure that you have plenty of pads so that you don't go metal to metal. Because when the brakes wear out that's what they do, the metal backing plates go against and they score up the discs really bad. You check the thickness of your pads, and in the thickness here you would want no less than, say, 1mm of pad surface left here and you would also want to make sure if you're doing it, a general rule of thumb is, 'is there enough pad to make it to the next service?' Because if there's not, the costumer will probably end up running it metal to metal, so you always want to make sure that there's at least that much pad. Another thing that needs to be checked, there's the grease-circs, there's the grease-circs up here on the front too, and there's also the front CV boot, which is right here on the outer and there's also the front CV boots here on the inner and just like the back, they can't have any holes in them, they can't have any oil leaks of any kind. Also on these units there's a lower ball joint right here, and this lower ball joint gets grease and it also, the nut on the bottom of it sometimes, even with a cotter key, there will be play and it'll get loose, and you want to check this lower ball joint for any play in it to make sure that it doesn't need to be replaced and it's not worn out. Also the rubber bushings up here, all the rubber bushings all the way around the unit need to be inspected too, to make sure they're okay.
